Running Monowall 1.231. PPTP is working great on XP, but I couldn't get it to work under Vista.
After some research I found this KB article:
I modified the the registry to set AllowPPTPWeakCrypto key to "1". After reboot, PPTP works.
According to the KB article, this is the reason for the change:
This behavior occurs because Windows Vista does not have
default support for the 40-bit and for the 56-bit encryption
levels under the RC4 algorithm. By default, Windows Vista
supports 128-bit encryption.
While this registry change works, I'd rather use the stronger encryption. Is there any way to
enable 128-bit encryption under Monowall?
